Three first-team players will be available for West Ham clash.
The likes of Reece James, Timo Werner and Jorginho are in contention for Saturday’s game against the Hammers.
Reece James missed Chelsea’s win over Watford earlier this week.
Tuchel said: ‘Jorginho, Timo Werner and Reece James are training and available. We did not train with Mateo Kovacic, N’Golo, Ben Chilwell and Trevoh Chalobah today, and they are all out.
‘It’s a lot of midfield players. We have missed Kova for many weeks, and also NG. Ben Chilwell is a long one. For Trevoh we need more examinations to see how bad the injury is.’
‘It’s important to have Reece and Jorgi back,’ added Tuchel.
‘Reece is the specialist on the side. Jorgi is the guy left from the three of him, Kova and NG on whose shoulders we put the central role over a long period.
‘We can’t wait to have Kova and NG to come back because they are a very important part of our team in a midfield role where we miss experience and leadership qualities.
‘But we will never complain, we are here to find solutions. If we miss players, other players will play and they have a contract here because they deserve it. We will have a strong team on the pitch tomorrow.’
